                                Depending on where you live, a standard 'cup' can vary significantly; for instance, a metric cup is defined as exactly 250ml in many countries, but a US customary cup is a different volume entirely. The seemingly simple question, "Is regular cup 250ml?" has a surprisingly complex answer due to a lack of global standardization.
